Sonohysterogram

An SHG (sonohysterogram), also known as SIS (saline infusion sonography) is special type of pelvic ultrasound in which the sonogram is followed by injection of sterile saline (salt water) into the uterus. By filling the uterine cavity and creating contrast, abnormalities in the uterine lining such as submucus fibroids and polyps become easier to see. In our center, we 3-D imaging which enables us to pick up uterine abnormalities that might otherwise be missed.
